To all whom, it 75m/,y concern:

Be a known that I, ROBERT J.- Rona, a

citizenofthe United States, residing at Cuy-v ahoga Falls, in the county of Summit and State of Ohiohave invented a-.certain new and useful Improvement in Feeding Devices,

'i of which thefollowingis a full, cle'ar, and eX- act description, reference being had to the avc-- companying drawings.

The object ofthe invention which'forms the subject` of'this application vis to provide an efiicient hopper and feeding means for the purlpose of supplying blanks to an operatingtOo In the embodiment of'my invention illustrate'd in the 4accompanying drawings and blank. 'This opening vantages.

Also it has been found in machines assume an uneven' owing to inaccuracy of this character when the tapping-toons retracted andreversed'in its rotary movement for the purpose of removing the-nut with the cooperating of a stationary Wrench the nut sometimes sticks in the walls ofthe stationarywrench and does not fall out in suflicient,`

time to clear the reciprocating carrier. This and many other similardisadvantages my invention is designed to 'obviate by means and mechanisms fully set out and described.

Referring to the accompanyingv drawings,

The" reciprocating "carriage C rides on iangesB in the bed-plate and may be limit- -tool F and the mouth of a om a hopper E, containing ed in its forward and backward movements 8o by the adjustable stops B2 B3. The carriage is channeled out infproper manner to receive Ia disk plate C2, which is provided i with a number of holes C3,

The holding-socket, as shownin the strucy yt ure ,.is provi ed on the forward side with retaining-lugs Cl -in.order to prevent too great a forward latter is fed thereinto. "The holding-block C5 is provided with a central longitudinal groove .on'its upper face, which serves to act as a arranged on different f radii about its periphery. These holes C38 Theblock *Cl 9 disk in place with -a positioning-socket tapping-tool is at o5 movement by the blank when the roo guide for the blanks being fed from the chute I' D into the positioning-socket, and is likewise provide-d on its under face with a longitudinal central groove for the purpose' of receiving a cleaning-blade H, hereinafter to be described.

The chute D ispreferably pivotally sup- 1ro away from both' the A.tween the plate EZ ported upon a bracket D and held at its upper end-,against the exit-orifice of the hopper by means of any suitable support, such as the horizontally-swingingv spring-arm D2., In front of the channel of the chute is a retaining-strip D3, suitably secured thereto in'any lpreferred manner, -whi'leat the lower end of the-chute is a curved guiding-tongue D, beneath which is a retaining-spring D5. By having the chute pivote it may be swung hopper and the carriage for cleaning and to reinoveany chips or other' obstructions tending to clogtlie-passage-way.

The hopper E, from whiclithe blanks are` fed into the chute, is suitably supported upon Yside framesE E and' has a bottomplate E2, secured beneath and the bottom of the hopper is a thin wearing-plate` E3, acrosswhich travels the sliding gate E4, provided withl a slot'Ei, controlling. the exit-orifice aforesaid.

nected so as shown, this shaft F end of which forms a Invthe upper part of the hopper isa reciprocating barEG, from whichdepends a stirringvrod E7, designed'to agitatethe blanks and cause their continuous freed-through the -slotted opening E5. i

The bar E6 and the vgate E4 extend beyondl the .hopper and are operated by any sui-table means, suchas the rocking arm E8. (Shown in Fig. 4.) One Aof these parts, veither the bar or, as in the machine shown, the gate E4, is

F T hev same I positivelydriven 'mechanism may also be utilized-for operating `the reciprocating carriage C. As: operates within a post F3,` suitably arched at its base to permit the rotation of a cam F. At the upper .ond ofthe' shaft F andv above the p ost F3 is another cam F2. Projecting from the side of the post, as shown in` Fig. 1, is a bracket F7, the upper fulci'um for the lever F5, one end of which is provided .with an anti-` .friction-roller held against the cam F2 bv means of the spring F4.

The other end ofthe lever F5 is connected with the extension-rod E, so that the operation of the caiirF2-teiids. to throw tliis'said rod inwardly toward the hopper through the medium of 'a cushioningspring E1", provided between the' endof the .lever F5 and a shoulder on the extension-rod Ef.

The other end of said lever isprovided with a yoke fitting over a bolt or similar projection extending from the car- ,riagey C and bearing against a cushioned' spring F3.

'These cushioned springs EN and F9 `are interposed between the cam and the theeXit-orifice. Be-

`Mounted upon the carriage C and moving therewith are angle-pieces K, overlapping the block C5 and serving to holdthe same, ltogether with the vdisk C2, carriage'.
